The aim of this study is to get the hydrogen production by batch solid state anaerobic fermentation from organic wastes, using cow manure as bacteria source, sewage sludge as nutrient supplier, simulated food residues as substrate, etc. The organic waste contains lower moisture, which not only can promote the organic loading but also reduce the waste organic acid liquidity, such as ethanoic, propionic, and butyric, etc. This study focuses on hydrogen production effective factors setting as constant temperature, allocated proportion, and substrate pretreatment. The results may infer to the adaptive operation for hydrogen fermentation processing.
In constant temperature experiment, the temperature variables for bacteria screening were setting between 50℃ and 80℃, separated by 5℃increments. From this series, seven thermophilic genera of bacteria were generated and each patch was subjected to 80 hours of thermophilic anaerobic fermentation at its respective constant temperature. The results show that 60℃ series had a noticeable specific hydrogen yield and specific hydrogen conversion rate 39 mL-H2/g-VS and 4.00 g-H2/g-H of VS%, respectively. Furthermore, the batch exponential hydrogen production stage can induce the continued stirrer thermal reactor (CSTR), which has optimal setting temperature in 65℃. In allocated proportion experiment, the slurry mixture was prepared by mixing proportion of cow manure and sewage sludge. The results show that the cow manure 500g, sewage sludge 1000g, and simulated food residues 500g have optimal hydrogen accumulate volume 9049 ml. In pretreatment experiment, the substrates indulge in acid, alkali, heat, and agitation process, respectively. The results show that alkali, heat, and agitation processing can upgrade hydrogen production efficiency except acid treatment. Herein, the alkali treatment can reduce react time from 50 hours to 25 hours; by the way, simulating hydrogen production rate can promote 359ml/hr to 1600ml/hr in CSTR.
